With the Arizona (anti-)immigration laws coming into affect soon, I have seen a lot of arguments in favor of immigration by those opposed to the Arizona laws. Most of them are either weak on economics, or miss the point completely. As a strong supporter of immigration, I thought I'd give two of my favorite arguments in favor of immigration.
My favorite argument in favor of immigration is that immigration is a huge boom to the immigrants themselves. It is, without a doubt, the strongest poverty alleviation tool in the history of man. Nothing else, no social program, no foreign aid, no economic reform, nothing, can so positively improve the lives of people like the freedom of an immigrant to move from an underdeveloped country to a developed country. The only way immigration is even debatable on humanitarian grounds is for one to assign almost zero importance to the welfare of the immigrants themselves. The argument is made stronger when you consider that immigrants also have a (small) net positive affect on the developed country. But even if you disagree, and believe that immigrants are a net loss to the receiving country, that loss would still have to be weighed against the overwhelming positive gain it gives immigrants themselves, almost always of which consist of the poorest members of the world. An impossible hurdle to overcome.
My second favorite argument in support of immigration, and this one specifically appeals to my libertarian and conservative friends, is that immigration is mutually exclusive from social programs. You have to pick: either an economy with abundant immigrants and low levels of social programs, or an economy with abundant social programs and low levels of immigrants. You can't have both. Counter intuitive you say?
Not really:
Although poor immigrants are likely to support a bigger welfare state than natives do, the presence of poor immigrants makes natives turn against the welfare state. Why would this be? As a rule, people are happy to vote to "take care of their own"; that's what the welfare state is all about. So when the poor are culturally very similar to the rich, as they are in places like Denmark and Sweden, support for the welfare state tends to be uniformly strong.
As the poor become more culturally distant from the rich, however, support for the welfare state becomes weaker and less uniform. There is good evidence, for example, that support for the welfare state is weaker in the U.S. than in Europe because our poor are disproportionately black. Since white Americans don't identify with black Americans to the same degree that rich Danes identify with poor Danes, most Americans are comfortable having a relatively small welfare state.
Thus, even though black Americans are unusually supportive of the welfare state, it is entirely possible that the presence of black Americans has on net made our welfare state smaller by eroding white support for it.
Immigration is likely to have an even stronger counter-balancing effect on natives' policy preferences because, as far as most Americans are concerned, immigrants from Latin American are much more of an "out-group" than American blacks. Faced with the choice to either cut social services or give "a bunch of foreigners" equal access, natives will lean in the direction of cuts. In fact, I can't think of anything more likely to make natives turn against the welfare state than forcing them to choose between (a) helping no one, and (b) helping everyone regardless of national origin.
This is not something peculiar to one blogger, this is widely recognized on the left and the right. From
Paul Krugman and
Matthew Yglesias on the left, to
Bryan Caplan,
Jeffrey Miron and
David Friedman (also

Taking the side of immigration over safety nets doesn't just make sense economically, it also makes sense on humanitarian grounds. As
Bryan Caplan explained: "...unlike the welfare state, immigration has and continues to help absolutely poor people, not relatively poor Americans who are already at the 90th percentile of the world income distribution. There's no reason for libertarians to make apologies to social democrats: Libertarian defenders of immigration are the real humanitarians in the world, and the laissez-faire era of open borders without the welfare state was America's real humanitarian era."
